Blockchain is built for protecting information, one of its major selling points. But VISHAL BARAPATRE – Chief Technical Officer at In2IT Technologies, asks what effect the PoPI act have on it.
The Protection of Personal Information (PoPI) Act is looming on our horizon. South African organisations are busily preparing for it despite there still being much debate about what the real impact will be and whether or not it will be truly effective. However, one thing is certain, a legislation that protects personal information (that is, any information relating to an identifiable, living person) is necessary, and any technology which could support PoPI within the business should be seriously considered.
One technology that seems purposefully built for protecting information is the blockchain. Although one of the selling points of blockchain technology is its inherent transparency, it certainly has effective security measures. This begs the question, could the transparency of blockchain technology conflict with the regulations that PoPI lays out, or does it add another mechanism for compliancy?
The blockchain, and PoPI compliancy
With the implementation of PoPI, organisations will need to be more sensitive around the privacy of their customers’ information – or be penalised. To do so, they will have to be more organised around the storage, use and dissemination of this data so as not to overstep the bounds of PoPI, and to take care of their customers’ privacy. There needs to be a level of ‘proof’ of where the data is kept, how it is used and who has access to it at any given time. This requirement fits in with the purpose of the blockchain: to provide a verifiable record of any data transaction, including who accesses the said data.
The blockchain is a shared digital transactional ledger that securely records and regularly reconciles transactions of virtually anything of value. Therefore, Blockchain provides accurate traceability and in turn, promotes accountability. Essentially, what the blockchain does for data storage is provide ratified certainty that all the due diligences have been conducted around a piece of data, and a means for recourse should data be unlawfully used or accessed.
There is also the security factor, which appeals to compliancy requirements of PoPI. The blockchain offers unparalleled security features, given its multi-verification nature and tamper proof mechanism of protecting already verified data. If current trends are anything to go by, the blockchain will only get more secure, which makes it ideal for use as a potentially impenetrable storage mechanism.
The question around transparency still exists. Surely a platform that specifically highlights transparency as a benefit automatically precludes it from being suitable for an act which stresses the protection of a person’s privacy? Not necessarily…
A blockchain can be programmed with certain pre-defined rules, or permissible actions, around what may be done with any piece of personal information, based on the type of information it is. Although the information may be visible to anyone with access to the blockchain on which it sits, these parameters automatically create alerts when certain data is accessed, used, or disseminated in any way that falls outside their bounds.
Granted, there is still the risk that the data may be accessed by unauthorised individuals, but the organisation will be alerted and can take immediate action. The blockchain provides verifiable proof of who accessed the data illegally, for what reason, and what was done with the data. It can then be raised with the PoPI regulator, if required, or can take internal action, as desired (or as required by policy and/or law).
The only real grey area with using the blockchain for complying with data storage, is that there will exist a permanent, in-erasable record of the data, indefinitely. PoPI does define that an organisation must honour an individual’s request for their data to be removed once it is no longer in use. The immutability of the blockchain could prove a problem, nevertheless an organisation still retains control of who may or may not access the data, and could exercise that control to ensure that the data remains all but invisible for its lifespan.
Android Go puts reliable smartphones in budget pockets
Nokia, Vodacom and Huawei have all launched entry-level smartphones running the Android Go edition, and all deliver a smooth experience, writes BRYAN TURNER.
Three new and notable Android Go smartphones have recently hit the market, namely the Nokia 1, the Vodafone Smart Kicka 4 and the Huawei Y3 (2018). These phones run one of the most basic versions of Android while still delivering a fairly smooth user experience.
Historically, consumers purchasing smartphones in the budget bracket would have a hit-and-miss experience with processing speed, smoothness of user interface, and app stability. The Google-supported Android Go edition operating system optimises the user experience by stripping out non-important visual effects to speed up the phone. Thish allows for more memory to be used by apps.
Google also ensures that all smartphones running Android Go will receive feature and security updates as they are released by Google. This is a major selling point for these smartphones, as users of this smartphone will always be running the latest software, with virtually no manufacturer bloatware.
Vodafone Smart Kicka 4
At the lowest entry-level, the Vodafone Smart Kicka 4 performs well as a communicator for emails and WhatsApp messages. The 4” screen represents a step up for entry-level Android phones, which were previously standardised at 3.5”.
The display is bright and very responsive, while the limited screen real estate leaves the navigation keys off the screen as touch buttons. It uses 3G connectivity, which might seem like an outdated technology, but is good enough to stream SD videos and music. Vodacom has also thrown in some data gifts if the smartphone is activated before the end of September 2018.
Its camera functionalities might be a slight let down for the aspirant Instagrammer, with a 2MP rear flash camera and a 0.3MP selfie snapper. Speed wise, the keyboard pops up quickly, which is a huge improvement from the Smart Kicka 3. However, this phone will not play well with graphics-intensive games.
Next up is the Nokia 1, which adds a much better 5MP camera, improved battery life and a bigger 4.5” screen. It supports LTE, which allows this smartphone to download and upload at the speed of flagships. It also sports the Nokia brand name, which many consumers trust.
Although the front camera is 2MP, the quality is extremely grainy, even with good lighting. This disqualifies this smartphone for the social media selfie snapper, but the 5MP rear camera will work for the landscape and portrait photographer.
The screen also redeems this smartphone, providing a display which represents colours truly and has great viewing angles. Xpress-on back covers allows the use of interchangeable, multi-coloured back covers, which has proven to be a successful sales point for mid-range smartphones in the past.
Huawei Y3 (2018)
The most capable of the Android Go edition competitors, the Huawei Y3 (2018) packs an even bigger screen at 5”, as well as an improved 8MP rear camera and HD video recording. The screen is the brightest and most vibrant of the three smartphones, but seems to be calibrated to show colours a little more saturated than they actually are.
Nevertheless, the camera outperforms the other smartphones with good colour replication and great selfie capabilities via the 2MP front camera – far superior to the Nokia 1 despite the same spec. LTE also comes standard with this smartphone and Vodacom throws in 4G/LTE data goodies until the end of September 2018. The battery, however, is not removable and may only be replaced by a warranty technician.
Comparing the 3
All three smartphones have removable back covers, which provide access to the battery, SIM card and SD card slots. The smartphones have Micro USB ports on the bottom with headphone jacks on the top. The built-in speakers all performed well, with the Y3 (2018) housing an exceptionally loud built-in speaker.
Although all at different price points, all three phones remain similar in performance and speed. The differentiators are apparent in the components, like camera quality and screen quality. It would be fair to rank the quality of the camera and battery life by respective market prices. The Vodafone Smart Kicka 4 performed well, for its R399 retail price. The Nokia 1, on the other hand, lags quite a bit in features when compared to the Huawei Y3 (2018), bwith oth retailing at R999.
SA gets digital archive
As the world entered the centenary of Nelson Mandela’s birth on Mandela Day, 18 July 2018, South Africa celebrated the launch of a digital living archive.
The southafrica.co.za site carries content about the country’s collective heritage in South Africa’s eleven official languages.
Designed as a nation building, educational and brand promotion web based tool, the free-to-view platform features award-winning photographic and written content by leading South African photographers, authors, academics and photojournalists.
The emphasis is on quality, credible, factual content that celebrates a collective heritage in terms of the following: Cultural Heritage; Natural Heritage; Education; History; Agriculture; Industry; Mining; and Travel.
At the same time as reflecting on the nation’s history, southafrica.co.za celebrates South Africa’s natural, cultural and economic assets so that the youth can learn about their nation in their home language.
Southafrica.co.za Founder and CEO Hans Gerrizen conceptualised southafrica.co.za as a means for youth and communities from outlying areas to benefit from the digital age in terms of the web tool’s empowering educational component.
“We can only stand to deepen our collective experience of democracy and become a more forward planning nation if we know facts about our nation’s past and present in everyone’s home language,” he says.
Southafrica.co.za, with sister company Siyabona Africa, is the organiser and sponsor of the Mandela: 100 Moments photographic exhibition that runs until 30 September at Cape Town’s V&A Waterfront-based Nelson Mandela Gateway to Robben Island. The 3-month exhibition, which runs daily from 08h00 until 15h00, is showcasing one hundred iconic Nelson Mandela images taken by veteran South African photojournalist and self-taught lensman Peter Magubane.
